Description

clear colorless to pale yellow liquid Acetylene dichloride is a colorless liquid (usually a mixture of the cis and trans isomers) with a slightly acrid, chloroform-like odor. It is incompatible with strong oxidizers, strong alkalis, potassium hydroxide, and copper. Acetylene dichloride is highly flammable and in a fi re gives off irritating or toxic fumes/gases. (Acetylene dichloride usually contains inhibitors to prevent polymerization.) 1,2-Dichloroethylene exists in three isomers, sym-, cis-

1,2-Dichloroethylene Use and Manufacturing

Methods of Manufacturing

It is obtained from 1, 1, 2, 2-tetrachloroethane by dechlorination of zinc powder or iron powder; it can also be prepared by the reaction of acetylene and chlorine in an inert solvent; it can also be obtained by 1, 1, 2-trichloroethane It is obtained by cracking copper chloride contained on pumice stone.

Uses

It can be used as a solvent for paints, resins, waxes, rubbers, and cellulose acetate. It can be used in dry cleaning agents, insecticides, fungicides, anesthetics, low-temperature extractants, and refrigerants.
